Oribatid mites (Acari: Oribatida) of hygrophyte grasslands on Transcarpathian Lowland

Fauna and ecological diversity of oribatid mites of hygrophyte grasslands on Transcarpathian lowland is considered in the paper. For Transcarpathia, such studies have not been conducted before. For hygrophyte grasslands 45 species of Oribatida (25 families, 34 families) are registered. The most numerous among detected taxa were Platynothrus peltifer, Ceratozetes mediocris and Oppiella nova. It has been established that dominant role belongs to the surface-soil morpho-ecological group of oribatid mites. In the ecological structure, predominant role is inherent of hydrophilous and eurytopic species.
